Have Truck Repair Questions? Ask an Expert
hi im alex, could i have your engine SN please
ok thanks, ***** ***** know what code is coming up? are you having to do more than one parked regen a day?
has the doc/dpf been removed and inspected at all? checked for exhaust leaks
ok so you get it to the dealer and they run a manual regen and all the temps are good?
ahh man thats tough seems to be how it always goes though, never act up at the dealer
does this happen after idiling a while or like at random
yes any emission related code could put the engine in to a derate, thats the EPAs way of getting people to bring there trucks in for service
some times it takes a few drive cycles of the code active to derate the engine this is all ecm based
being from a dealership i have not done any , i know companys do it, you send ecm in and they program and send it back for you modifications but that is all i really know,
i guess this will be hard to determine why the light comes on if you run a regen and it is fine at the dealer, i would assume its a temp sensor issue because usually if it is a DPF or DOC issue it will happen all the time and not at random
please remember to rate my service , i receive no compensation until you rate me, i will continue to help you after rating so rate with confidence thanks
